Double screw versus angular stable plate fixation of scaphoid waist nonunions in combination with intraoperativeextracorporeal shockwave therapy (ESWT).

Over the past years, different fixation techniques focused on rotational stability in order to increase stability and stimulate union rates. Additionally, extracorporeal shockwave therapy (ESWT) has gained importance in the treatment of delayed and nonunions. Purpose of this study was to compare the radiological and clinical outcome of two headless compression screws (HCS) and plate fixation in scaphoid nonunions, in combination with intraoperative high energy ESWT. Thirty-eight patients with scaphoid nonunions were treated by using a nonvascularized bone graft from the iliac crest and stabilization with either two HCS or a volar angular stable scaphoid plate. All patients received one ESWT session with 3000 impulses and energy flux per pulse of 0.41mJ/mm2 intraoperatively. Clinical assessment included range of motion (ROM), pain according to the Visual Analog Scale (VAS), grip strength, disability of the Arm Shoulder and Hand Score, Patient-Rated Wrist Evaluation Score, Michigan Hand Outcomes Questionnaire and modified Green O'Brien (Mayo) Wrist Score. To confirm union, a CT scan of the wrist was performed. Thirty-two patients returned for clinical and radiological examination. Out of these, 29 (91%) showed bony union. All patients treated with two HCS compared to 16 out of 19 (84%) patients treated by plate showed bony union on the CT scans. The difference was not statistically significant.However, at a mean follow-up interval of 34months, no significant differences could be found in ROM, pain, grip strength and patient-reported outcome measurements between the two HCS and plate group. Height-to-length ratio and capitolunate angle improved significantly in both groups compared to preoperative. Scaphoid nonunion stabilization by using two HCS or angular stable volar plate fixation and intraoperative ESWT results in comparable high union rates and good functional outcome. Due to the higher rate for a secondary intervention (plate removal), HCS might be preferable as first choice, whereas the scaphoid plate fixation should be reserved for recalcitrant (substantial bone loss, humpback deformity or failed prior surgical intervention) scaphoid nonunions.

Clinical Outcomes of Arthroscopic-Assisted Volar Scapholunate Capsulodesis: A Case Series.

Purpose We have previously described arthroscopic-assisted volar scapholunate (SL) capsulodesis as an alternative technique for addressing volar SL interosseous ligament (SLIL) injuries. In this article, we report the outcomes of this procedure in a cohort of patients. Methods Postoperative outcomes including range of motion, grip strength, visual analog scale (VAS) pain score, Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH), and Mayo Wrist Score were assessed through a prospective review of six patients in a single center who underwent this procedure. Results Six patients (four male and two female) with a mean age of 43 ± 14 years were evaluated in the study. The mean duration of follow-up was 41 ± 17 weeks. Postoperative outcomes noted a reduction in VAS pain score from 8 before surgery to 0.7 postoperatively ( p = 0.00004) and improvement in Mayo Wrist Score (42 preoperatively to 80 postoperatively; p = 0.001), grip strength (86% of contralateral side; p = 0.20), and flexion arc (81% of contralateral side; p = 0.08). QuickDASH was 20 ± 8 and Patient-Rated Wrist Evaluation score was 13 ± 2 at the last clinical follow-up. There was an improvement in SL gap ( p = 0.03), SL angle ( p = 0.11), and radiolunate angle ( p = 0.15) measurements postoperatively. Conclusions The described arthroscopic-assisted volar SL capsulodesis in this study presents an alternative method to address volar SLIL pathology with positive short-term clinical outcomes. Clinical Relevance Arthroscopic-assisted volar SL capsulodesis may be considered in the treatment algorithm for volar SLIL injuries.

Clinical outcomes of double-screw fixation with bone grafting for displaced scaphoid nonunions: Aseries of 21 cases.

This study reports the clinical outcomes of double-screw fixation with bone grafting for displaced scaphoid nonunions. This study was a retrospective survey. From January 2018 to December 2019, 21 patients with displaced scaphoid fractures underwent open debridement and two headless compression screw fixation with bone grafting. The preoperative and postoperative lateral intrascaphoid angle (LISA) and scapholunate angle (SLA) were recorded. Preoperative and postoperative grip strength (% of the healthy side), active range of motion (AROM), visual analogue scale (VAS), and patient-rated wrist evaluation (PRWE) scores at the final follow-up were obtained for all patients for comparison. Patients were treated for an average of 38.3 months (range 12-250) after the injury. The average time of postoperative follow-up was 30.5 months (range 24-48). All fractures achieved union at a mean of 2.7 months (range 2-4) after surgery, and 14 scaphoids of 21 patients (66.7%) healed by 8 weeks. CT scans showed no evidence of cortical penetration of either screw in all patients. There was a statistically significant improvement in AROM, grip strength, and PRWE. No complications occurred in this study, and all patients returned to work. This study indicates that double-screw fixation with bone grafting is an effective technique for treating displaced scaphoid nonunions.

Clinical, Radiographic, and Patient-Perceived Outcome After Radial Hemi-Wrist Arthroplasty With a New Implant: 20 Cases With 5-Year Follow-up.

Distal component loosening is a common mode of failure in total wrist arthroplasty (TWA). A radial hemi-wrist arthroplasty (RHWA) has the potential to avoid problems related to the distal component in TWA. The aim of this study is to investigate clinical outcomes following surgical treatment with a new RHWA design. In this pilot study of 20 consecutive RHWAs, patients were assessed preoperatively and postoperatively for range of motion, grip strength, Visual Analog Scale (VAS) pain scores, and functional scoring using Patient-Rated Wrist Evaluation (PRWE), Disabilities of the Arm, Shoulder, and Hand (DASH), and Canadian Occupational Performance Measure. Radiographs were analyzed at 12 months and 5 years (mean, 5.1 years) postoperatively. A total of 46 secondary surgeries were undertaken in 16 wrists, including 7 revisions. Another 6 patients are waiting for revision to radiocarpal arthrodesis. In non-revised patients, the DASH and PRWE scores improved, and wrist range of motion remained largely unchanged except for wrist flexion, which decreased. The VAS pain score during activity was reduced, and hand grip strength remained largely unchanged. The new implant resulted in improved functional scoring and improved VAS pain scores in non-revised patients, but many cases needed secondary surgery due to persistent pain. The high revision rate is a major concern, and further use of the implant in its current form cannot be recommended.

Arthroscopic treatment of unstable scaphoid fracture and nonunion with two headless compression screws and distal radius bone graft

BackgroundThe treatment of unstable scaphoid fracture and nonunion remains a challenging problem for hand surgeons. Minimally invasive treatment has become the preferred method of treatment.PurposeThis study introduces the arthroscopic technique with two headless compression screws (HCS) fixation and distal radius bone grafting for the treatment of unstable scaphoid fracture and nonunion, aiming to evaluate its clinical and radiological outcomes.MethodsIt was a retrospective study. From January 2019 to February 2021, a total of 23 patients were included in the current study. Among them, 13 patients with unstable scaphoid fracture underwent arthroscopic treatment with two HCS; 10 patients with scaphoid nonunion underwent arthroscopic treatment with two HCS and a distal radius bone graft. The range of motion of the wrist, visual analog scale (VAS), grip strength, the Modified Mayo Wrist Score (MMWS), the Patient-Rated Wrist Evaluation (PRWE) score, and the Disability of the Arm, Shoulder and Hand (DASH) score were collected at preoperatively and the final follow-up. A computed tomography scan of the wrist was performed on each patient to analyze for union and postoperative osteoarthritis during the follow-up period.ResultsSignificant improvement was only observed in wrist extension. Clinical outcomes including grip strength, VAS pain score, MMWS, PRWE score, and DASH score were significantly improved at the final follow-up. In the subgroup analysis, both patients stabilized with either two HCS or a distal radius bone graft and two HCS have improved clinical outcomes after surgery, respectively. All patients achieved union. No screw fixation failure occurred, and no other postoperative complication was observed in any of the patients.ConclusionsThe arthroscopic technique with two-HCS fixation and distal radius bone grafting is a reliable and effective technique for the treatment of unstable scaphoid fracture and nonunion, providing satisfactory union rates and clinical outcomes.

Ligamentoplasty using the ulnotriquetral ligament with wafer procedure for chronic triangular fibrocartilage complex foveal tear: Short-tem outcome

BackgroundWe developed a new ligamentoplasty technique using the ulnotriquetral ligament (UTL) via a palmar approach for cases with dorsal instability of the ulna due to a foveal tear of the triangular fibrocartilage complex (TFCC). The study aimed to evaluate the clinical outcomes of this procedure. MethodsWe retrospectively analyzed 19 cases with foveal tears of TFCC who underwent the ligamentoplasty using UTL. We harvested the UTL from the triquetrum as a pedicle graft, avoiding damage of the connection between the base of the UTL and palmar radioulnar ligament (PRUL) as possible. The graft was flipped proximally and pulled out through the bone tunnel from the ulnar fovea to the ulnar neck, then fixed to the fovea using a tenodesis screw. The function of the TFCC can be reproduced by pulling out the UTL along with the PRUL through the ulnar fovea and re-establishing the PRUL tension. Clinical results were evaluated at least 12 months following surgery. The preoperative and postoperative wrist pain level on a neumerical rating scale (NRS), the radioulnar joint (DRUJ) ballottement test, the range of motion, the grip strength, and the Patient-rated wrist evaluation (PRWE) scores were evaluated. ResultsIn all cases, the DRUJ ballottement test became negative at the final follow up compared with the normal side on manual examination. The pain levels significantly decreased as reflected by a decrease in NRS from 6.8 to 2.5 at final follow up (p < 0.01). The range of pronation/supination motion was improved from 149° to 157°. The mean PRWE score significantly decreased from 52.1 to 22.8 (p < 0.01). The postoperative pain level on the NRS scale of the three patients poorly improved. One case of the three with the 3 mm positive ulnar variance needed additional ulnar shaft shortening using a plate seven months after the primary procedure. ConclusionsThe ligamentoplasty using UTL efficiently restored the ulnar palmar stability in all 19 cases and significantly decreased the wrist pain and the PRWE scores. Study designClinical, retrospective study.

Does open reduction internal fixation using a volar locking plate and closed reduction percutaneous pinning using K wires provide similar functional and radiological outcomes for unstable distal radius fractures?

Background: Distal radius fractures (DRFs) are a common orthopedic injury, with open reduction internal fixation (ORIF) and closed reduction percutaneous pinning (CRPP) being the two most frequently used methods for treating unstable DRFs. The optimal treatment approach for DRFs is still a matter of debate. Therefore, this retrospective analysis aimed to compare the functional and radiological outcomes of ORIF and CRPP to determine the most effective approach for treating unstable DRFs. Material and Methods: A total of 89 patients were included in this retrospective study; 34 underwent CRPP and 55 underwent ORIF (61 males and 28 females, mean age: 35.5). Radiographic measurements of radial inclination, radial height, and volar tilt, as well as patient-rated wrist evaluation (PRWE) scores for pain and function, were used to evaluate the functional and radiological outcomes during the final follow-up period, ranging from 1 to 4 years. Results: There were significant improvements in the radiographic measurements for both groups, indicating a good reduction. However, the two fixation methods had no significant difference in radiographic measurements during the entire follow-up period. Regarding PRWE scores, there was a significant difference between the two groups, with patients in the CRPP group reporting better wrist function and less pain. Conclusions: Both CRPP and ORIF are effective methods for treating unstable DRFs. Achieving an acceptable reduction did not correlate with better pain management, function, or the ability to carry out day-to-day activities. However, patients treated with CRPP had better wrist function and less pain during follow-up. Radiographic measurements did not differ significantly between the two groups. Clinicians should consider closed-reduction percutaneous pinning as a viable and effective treatment option for distal radius fractures, particularly when optimal wrist function and pain management are important considerations.

Prevalence of upper extremity pain and disability in elite football, ice hockey and floorball players

In athletes, injuries and medical conditions affecting the upper extremities are quite common. However, there has been limited research on the occurrence of joint pain in the peripheral upper extremities among elite athletes. Thus, this study aimed to determine how prevalent upper limb pain and disability are among team sports players, particularly in football, ice hockey and floorball. We also aimed to compare the severity of pain and disability among these sports and assess the risk of developing upper limb pain in athletes. This cross-sectional study was conducted between June 2021 and September 2022, involving 388 male elite athletes from national-level sports clubs. The prevalence of shoulder pain and disability was determined using the Shoulder Pain and Disability Index (SPI). Assessment of elbow pain and disability was conducted using the Oxford Elbow Score (OES), while wrist pain and disability were evaluated through the Patient-Rated Wrist Evaluation (PRWE). Significant differences in total SPI, OES and PRWE scores were observed among all groups. Ice hockey players experienced the highest levels of shoulder and wrist pain. Compared to football and floorball players, ice-hockey players had a 2.13 times higher risk of shoulder pain, with a pain incidence of 40.8%. Ice hockey also had a 1.71 times higher risk of wrist pain than football, with a pain prevalence of 26.3%. Notably, floorball players exhibited the most pronounced elbow pain, with a 13.18-fold higher risk than football and ice-hockey players and a pain prevalence of 67.2%. The study findings suggest that ice hockey players experience the highest pain levels in their right limbs, whereas football players have the lowest pain levels, underscoring the importance of dedicating more attention to developing innovative, effective and advanced preventive programs for athletes.

Patient Satisfaction with Pisiform Excision for Pisotriquetral Instability or Arthritis: A Prospective Review.

Background Pisotriquetral pain and instability is an elusive cause of ulnar-sided wrist pain. Initial treatment of chronic pisotriquetral pathology should involve a trial of nonoperative therapy such as neutral wrist splint, anti-inflammatories, and intra-articular steroid injections. The mainstay of surgical management of pisotriquetral pain is pisiform excision. Purpose This prospective study seeks to understand patient satisfaction after pisiform excision in patients with isolated pisotriquetral pathology. Patients and Methods A consecutive series of nine cases of pisiform excision was performed by the senior surgeon. The primary outcome measure was determined a priori to be the Patient-Rated Wrist Evaluation (PRWE) score. Wrist range of motion, grip strength, and QuickDASH (shortened version of Disabilities of the Arm, Shoulder and Hand) scores were also collected preoperatively and at 3 and 12 months postoperatively as secondary outcome measures. Results There was a very rapid improvement in the PRWE by 3 months, which was maintained at 12 months. The QuickDASH score was slower to improve, with a significant improvement by 12 months. There was no change in grip strength or wrist range of motion at any time point. Conclusion Pisiform excision results in a very rapid improvement of symptoms and should be considered in cases of pisotriquetral instability or arthritis that fail conservative management. Level of Evidence Level IV, case series.

Clinical and functional analysis of closed reduction-plastering and volar locking plate methods in distal radius fractures in patients over 60 years of age

Aim: Many different methods have been described in the treatment of distal radius fractures (DRF) in the elderly population, and which one is the better method is a matter of debate among orthopedic surgeons. The aim of this study was to compare the results of closed reduction and plastering (CRP) and volar locking plate (VLP), which are used in the treatment of DRF in the elderly population. Materials and Methods: Between January 2019 and December 2020, 36 patients with DRF aged &amp;gt; 60 years were evaluated retrospectively. There were 19 patients in the CRP group and 17 patients in the VLP group. Wrist flexion, extension, pronation, supination, ulnar deviation, and radial deviation degrees and grip strength were measured in the first year of their treatment. The patients were evaluated functionally by patient-rated wrist evaluation (PRWE), modified Green and O'Brien score (MGOS), and resting and stress visual analogue scale (VAS). Results: In both groups, similar ROM values were obtained and no significant difference was observed. While the PRWE score was 17.5 ± 5.5 in the CRP group and 12.5 ± 4.8 in the VLP group, the MGOS score was 83.0 ± 7.4 in the CRP group and 86.8 ± 12.6 in the VLP group, and the scores were not significantly different (p = 0.802, p = 0.315). While there was almost no pain in both groups at rest, more pain was felt in the VKP group under stress. While grip strength was 20.9 ± 6.4 kg in the CRP group, it was 22.2 ± 6.8 kg in the VLP group, and there was no significant difference compared to the contralateral wrist. Conclusion: There is no clinical and functional difference between CRP and VLP in the one-year period after DRF treatment in the patient population aged &amp;gt; 60 years. Treatment should be planned according to the functional capacity of the patient.

Development and Validation of a Survey to Measure Patients' Expectations of Wrist Arthritis Surgery.

Background The purpose of this study was to develop and test a patient-derived expectations survey for wrist arthritis surgery. We hypothesized that preoperative patient expectations are higher in people with greater functional impairment and that postoperative fulfilment of patient expectations correlates with functional improvement. Methods The study was conducted in four phases. Development (n = 22) Preoperatively, patients were asked open-ended questions regarding expectations of surgery. A draft survey was then assembled. Reliability (n = 35) The survey was administered twice preoperatively. Concordance was measured with weighted kappa values and intraclass correlations (ICC). Validity (n = 58) Validity was assessed by comparing responses from the Expectations Survey to the patient-rated wrist evaluation (PRWE). Responsiveness (n = 18) Responsiveness was calculated by comparing the proportion of expectations fulfilled to PRWE scores 1-year postoperatively. Results Development Twenty-two distinct items representing the most frequent responses were utilized from the draft survey items of 1,244 expectations volunteered. Reliability Patients had high preoperative expectations of surgery (mean = 76.8); 30% had scores ≥90. Test-retest reliability was high (Cronbach α coefficients = 0.91, 0.93, ICC = 0.86). Endorsement of items = 66 to 100%; and weighted kappa values = 0.39 to 0.96. Validity Patients with greater preoperative expectations (≥63) had more pain, worse function, and worse PRWE scores than those with lower expectations. Responsiveness The proportion of fulfilled expectations was high (mean 0.80, median 0.79), and greater fulfillment (proportion > 0.80, n = 8) was associated with better postoperative PRWE scores. Conclusion The patient-derived expectations survey is reliable, valid, responsive, and addresses a spectrum of expectations for patients undergoing surgery for wrist arthritis. Clinical relevance Understanding patient expectations can contribute to customized care given the range of surgical choices for the arthritic wrist.

Comparing Patient-Reported Outcomes on Three-Ligament Tenodesis Between Partial and Complete Scapholunate Ligament Injuries: A Cohort Study

Multiple studies report outcomes after 3-ligament tenodesis (3-LT) in treating traumatic scapholunate interosseous ligament injury (SLIL). However, investigators do not differentiate between patients with partial or complete SLIL injury. The relation between the extent of SLIL disruption and surgical outcomes and if this should be considered when treating a patient with SLIL injury remains unknown. We aimed to evaluate differences in patient-rated wrist evaluation (PRWE) scores, satisfaction and return to work between patients with partial or complete chronic traumatic SLIL injury treated with 3 ligament tenodesis at 12 months after surgery. All patients with chronic SLIL injury (partial and complete) who were treated with 3-LT at our clinic and received the same postoperative management between December 2011 and December 2019 were studied. Only patients who had completed the PRWE and return to work questionnaires preoperatively and 12 months after surgery were included. Patients were allocated to the partial (classified as Geissler 2 or 3) or complete SLIL injury group (classified as Geissler 4) by retrospectively assessing wrist arthroscopy reports. Thirty-nine patients with partial and 90 with complete SLIL injuries were included. At 1-year follow-up, PRWE scores had significantly improved in both groups. When adjusting for clinical baseline characteristics, there was no statistically significant difference between patients with partial or complete SLIL injury. Patients with complete SLIL injury had a 70% higher return to work within the first 12 months after 3-LT; however, satisfaction with the treatment result was similar for both study groups 1 year after surgery. Patients with complete and partial traumatic SLIL injury report better PRWE total scores at 12 months after 3-LT, but there was no statistically significant difference between the groups in PRWE scores or satisfaction with the treatment result. Therapeutic IV.

Comparison of Outcomes of Scapholunate Ligament Reconstruction Techniques.

Introduction Injury to the scapholunate interosseous ligament (SLIL) is a common cause of carpal instability, yet surgical management of chronic SLIL disruption remains challenging with no optimal technique identified. Purpose The purpose of this meta-analysis was to comparatively review the available evidence of clinical, radiographic, and patient-reported outcome measures among popular techniques of SLIL reconstruction (capsulodesis, tenodesis, and bone-tissue-bone graft) to better guide management of SLIL injuries. Methods A total of 1,172 patients from 42 included studies were assessed. Standardized data extraction and analysis were performed. The mean of postoperative outcome assessments with standard deviation was used to calculate pooled standardized mean difference with 95% confidence interval. Results Visual Analog Scale (VAS) score for postoperative pain was lowest in bone-tissue-bone patients at 0.9 ( p = 0.0360). Bone-tissue-bone patients had the highest percentage of "excellent" functional outcomes at 64.5% ( p < 0.0001). Disabilities of the Arm, Shoulder, and Hand (DASH)/QuickDASH score was best in bone-tissue-bone patients at 9.7 ( p < 0.0001). Patient-Rated Wrist Evaluation (PRWE) score was best in tenodesis patients at 37.8 ( p = 0.0255). There were no statistically significant differences in grip strength, range of motion, or radiographic outcomes among the techniques. Conclusion Existing data demonstrate some benefit of bone-tissue-bone reconstruction over capsulodesis and tenodesis in pain reduction and functional improvement of the injured wrist. No statistically significant differences among radiographic outcomes could be ascertained, possibly attributable to the heterogeneity of procedures. This review provides an updated reference and highlights the need for multicenter trials with longer term follow-up and more standardized outcome measures.

Effect of delayed distal radius fracture fixation on the difficulty of surgical operation

PurposeThe effect of delayed distal radius fracture (DRF) fixation by volar locking plates (VLPs) on the operative time, rate of bone graft use and need for additional surgical incisions was analyzed. Short- and mid-term outcomes were compared between early and delayed DRF fixation. MethodsA retrospective cohort review of DRFs treated with VLPs was performed. The effects of delayed fixation were analyzed by 1) comparing intraoperative and radiographic parameters and follow-up outcomes between early fixation (EF, 1–10 days) and late fixation (LF, ≥11 days), 2) predicting the prolonged operative time using linear regression analysis, and 3) predicting the rate of bone graft use and additional incision using odds ratios. ResultsOf 104 patients, 51 and 53 were in the EF and LF groups, respectively. EF showed a significantly shorter operative time, lower rate of bone grafting and fewer additional incisions (94.80 vs. 123 minutes, 3.92% vs. 26.18% and 2% vs. 20.45%, respectively). Radiographic parameters, immediate postoperative pain and wrist range of motion were significantly better in the EF group. However, the visual analog scale (VAS) pain and Patient-Rated Wrist Evaluation (PRWE) scores were not different at the 12-month follow-up. For every day of delay, the operation was prolonged by 2.17 min, the rate of bone grafting increased by 8%, and the chance of additional incisions increased by 8%. ConclusionDelayed DRF fixation affects intraoperative and postoperative outcomes. We encourage internal fixation for DRFs as early as possible to reduce surgical complexity and improve postoperative outcomes.

Four-Corner Arthrodesis with a Dorsal Locking PEEK Plate: A Retrospective Case Series.

Background Four-corner arthrodesis (4CA) can be performed with a variety of methods. To our knowledge, fewer than 125 cases of 4CA with a locking polyether ether ketone (PEEK) plate have been reported, necessitating further study. Purpose The purpose of this study was to evaluate the radiographic union rate and clinical outcomes in a series of patients who received 4CA with a locking PEEK plate. Methods We re-examined 39 wrists in 37 patients at a mean follow-up of 50 months (median: 52 months, range: 6-128). Patients completed the Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH), Patient-Rated Wrist Evaluation (PRWE), and participated in measurements of grip strength and range of motion. Anteroposterior, lateral, and oblique radiographs of the operative wrist were examined for union, screw breakage and/or loosening, and lunate change. Results The mean QuickDASH score was 24.4 and the mean PRWE score was 26.5. Mean grip strength was 29.2 kg or 84% of the nonoperative hand. Mean flexion, extension, radial deviation, and ulnar deviation were : 37.2, 28.9, 14.1, and 17.4 degrees, respectively. Eighty-seven percent of wrists achieved union; 8% had nonunion; and5% had indeterminate union. There were seven cases of screw breakage and seven cases of screw loosening (as defined by lucency or bony resorption surrounding screws). Twenty-three percent of wrists required reoperation (four total wrist arthrodesis and five reoperations for other reasons). Conclusion 4CA with a locking PEEK plate has clinical and radiographic outcomes similar to other methods. We observed a high rate of hardware complications. It is unclear whether this implant offers a clear advantage over other methods of fixation used in 4CA. Type of Study/Level of Evidence Level IV, therapeutic study.

A randomized controlled trial comparing two modern total wrist arthroplasties : improved function with stable implants, but high complication rates in non-rheumatoid wrists at two years.

To analyze the short-term outcome of two types of total wrist arthroplasty (TWA) in terms of wrist function, migration, and periprosthetic bone behaviour. A total of 40 patients suffering from non-rheumatoid wrist arthritis were enrolled in a randomized controlled trial comparing the ReMotion and Motec TWAs. Patient-rated and functional outcomes, radiological changes, blood metal ion levels, migration measured by model-based radiostereometric analysis (RSA), bone mineral density (BMD) measured by dual-energy X-ray absorptiometry (DXA), complications, loosening, and revision rates at two years were compared. Patient-Rated Wrist and Hand Evaluation (PRWHE) scores, abbreviated version of the Disabilities of the Arm, Shoulder and Hand questionnaire scores, and pain improved similarly and significantly in both groups. Wrist motion improved significantly in the Motec group only, and forearm rotation in the ReMotion group only. Cobalt (Co) and chromium (Cr) blood ion levels were significantly higher in the metal-on-metal (MoM) Motec group than in the metal-on-polyethylene (MoP) ReMotion group. Mean total translation was 0.65 mm (95% confidence interval (CI) 0.26 to 1.12) and 0.27 mm (95% CI 0.14 to 0.47) for the ReMotion carpal and radial components, and 0.32 mm (95% CI 0.22 to 0.45) and 0.26 mm (95% CI 0.20 to 0.34) for the Motec metacarpal and radial components, respectively. Apart from dorsal and volar tilts, which were significantly higher for the radial ReMotion than for the Motec component, no significant differences in absolute migration occurred. BMD around the radial components never returned to baseline. Almost one-third of patients required reoperation due to complications. Two ReMotion implants were revised to Motec TWAs due to carpal component loosening, and three Motec MoM articulations were revised to metal-on-polyether ether ketone due to painful synovitis. Both implants provided matched function and were stable at short-term follow-up, but with a high complication rate. This procedure should be restricted to specialist centres undertaking prospective analysis until its role is clarified.Cite this article: Bone Joint J2022;104-B(10):1132-1141.

Clinical Study of Wrist Arthroscopy Combined with Oblique Ulnar Shortening Osteotomy in the Treatment of Ulnar Impaction Syndrome.

To explore the clinical effects of wrist arthroscopy combined with oblique ulnar shortening osteotomy in the treatment of ulnar impaction syndrome. This was a retrospective study of 60 patients with ulnar impaction syndrome who were admitted to our department from January 2016 to December 2019. According to different surgical methods, they were divided into an observation group and a control group, with 30 cases in each group. The control group was treated with oblique ulnar shortening osteotomy, and the observation group used wrist arthroscopy based on the control group. The two groups of patients were compared in terms of wrist function before and 12months after surgery. We compared the Disabilities of the Arm, Shoulder, and Hand Score (DASH Score), Patient-Rated Wrist Evaluation Score (PRWE Score), Visual Analog Score (VAS), and ulnar variation between the two groups at 12months after surgery. The excellent and good rates by Mayo wrist score were compared between the two groups at the last follow-up. All patients were followed up for 12-36months, with an average of 14.5months. Bone union was achieved at the oblique osteotomy of the ulna, with an average healing time of 13.6 weeks. The observation group was examined by wrist arthroscopy, and the triangular fibrocartilage complex (TFCC) Palmer classification was confirmed in three cases of type IIA, seven cases of type IIB, 14 cases of type IIC, and six cases of type IID. Compared with before surgery, the grip strength, flexion-extension, ulnar radial deflection, and forearm rotation of the two groups of patients were significantly improved at 12months after surgery. The DASH score, PRWE score, and VAS score of the observation group were better than those of the control group, and the difference in ulnar shortening length was not statistically significant between the two groups. The excellent and good rates of the observation group (93.3%) were better than those of the control group (87.5%) at the last follow-up, and the difference was statistically significant. Compared with oblique ulnar shortening osteotomy alone, combined wrist arthroscopy can better reduce the pain of patients with ulnar impaction syndrome, restore wrist function, and improve the excellent and good rates. Therefore, it is clinically worthy of promotion.

Intra Articular Injection of Autologous Microfat and Platelets-Rich Plasma in the Treatment of Wrist Osteoarthritis: A Pilot Study.

No injection treatment has been proven to be effective in wrist osteoarthritis. When conservative measures fail, its management involves invasive surgery. Emergence of biotherapies based on adipose derived stem cells (ADSC) offers promising treatments for chondral degenerative diseases. Microfat (MF) and platelets-rich plasma (PRP) mixture, rich in growth factors and ADSC could be a minimally invasive injectable option in the treatment of wrist osteoarthritis. The aim of this uncontrolled prospective study was to evaluate the safety of a 4 mL autologous MF-PRP intra-articular injection, performed under local anesthesia. The secondary purpose was to describe the clinical and MRI results at 12 months of follow-up. Patients’ data collected were: occurrence of adverse effects, Visual analog scale (VAS), Disabilities of the Arm, Shoulder and Hand score (DASH) and Patient-Rated Wrist Evaluation (PRWE) scores, wrist strength, wrist range of motion and 5-level satisfaction scale. No serious adverse event was recorded. A statistically significant decrease in pain, DASH, PRWE and force was observed at each follow-up. Our preliminary results suggest that intra-articular autologous MF and PRP injection may be a new therapeutic strategy for wrist osteoarthritis resistant to medical symptomatic treatment prior to surgical interventions.

Residual flexion deformity after scaphoid nonunion surgery: 7-year follow-up study.

The clinical implication of a residual flexion deformity following surgery for scaphoid nonunion is unclear. Sixty-three patients who underwent scaphoid nonunion surgery were assessed after a mean of 7 years (range 5-10) to analyse the outcomes based on the presence of residual scaphoid deformity. Primary outcome was Disabilities of the Arm, Shoulder and Hand score. Secondary outcomes were Patient-Rated Wrist Evaluation score, wrist range of motion and strength. Patients were dichotomized to residual deformity or no deformity. Scaphoid deformity was calculated from CT scans based on the median difference between the height-length ratio of the operated versus the uninjured scaphoid. There were no differences between residual deformity (n = 33) and no deformity (n = 30) in any outcome variables, except for wrist extension which was slightly worse in the deformity group. The deformity group had a greater number of radiographic osteoarthritis, but all cases were mild, and osteoarthritis did not correlate to a worse outcome. We conclude that residual scaphoid deformity has no relevant negative impact on mid-term wrist function.Level of evidence: IV.

Treatment of Distal Radius Fractures with Bridging External Fixator with Optional Percutaneous K-Wires: What Are the Right Indications for Patient Age, Gender, Dominant Limb and Injury Pattern?

The aim of this retrospective study was to evaluate the medium-term clinical and functional outcomes of patients with closed, displaced, and unstable, simple or complex, intra- and extra-articular distal radius fractures (DRFs) treated with a bridging external fixator (BEF) and optional K-wires (KWs). AO classification was used to differentiate the injuries radiographically. Clinical-functional outcomes were evaluated using the Patient-Rated Wrist and Hand Evaluation Score (PRWHE Score) and the Quick Disabilities of the Arm Shoulder and Hand Score (QuickDASH). A total of 269 dorsally displaced fractures of 202 female (75%) and 67 male subjects (25%) were included, with a mean follow-up of 58.0 months. Seventy-five patients (28%) were treated by additional KWs. No differences were found comparing the two groups of patients (BEF vs. BEF + KWs) regarding age, sex, and fracture side (dominant vs. non-dominant). PRWHE and QuickDASH scores were lower in the BEF + KWs group compared to the BEF group (p < 0.0001 and p = 0.0007, respectively). Thus, patients treated with KWs had a better clinical outcome. Beta multivariate regression analysis confirmed that patients of the BEF + KWs group exhibited a better PRWHE score but not a better QuickDASH score. Patients treated by the BEF + KWs with the fracture on the dominant site were characterised by better clinical outcomes. Older patients had a better PRWHE score independently from the treatment. Our findings suggest that the use of BEF for DRFs with optional KWs can be indicated in both young and elderly patients of any gender, independent of limb side and fracture pattern. As the best functional results were achieved in the elderly when KWs were added, the combination of BEF and KWs seems to be mainly indicated for the treatment of DRF, also complex, in the elderly population.
